iPhone SE3 screen heavily

Thanks for the app, but I got the experience on my iPhone SE3 that

the screen is darkening very quickly !! Even if I shut down SkyDemon navigation and use SafeSky as only running application there is no amelioration - screen keeps nearly dark !
Any hints ? It happens only with SafeSky - airfuzzy

Your screen darkens depending on the exterior brightness. This a priori has nothing to do with SafeSky. We do not touch the phone settings regarding the brightness of the screen. If the sun is shining on the screen in flight, it will quickly darken. See your phone or iPad settings.
